Joseph diGenova, a former member of Donald Trump's legal team, has been added to the Justice Department's investigation into former CIA Director John Brennan. He will be assigned to Fort Pierce, Florida. This follows the dismissal of the Miami federal prosecutor who was leading the investigation after she resisted pressure to bring charges against Brennan. The investigation is being led by US Attorney Jason Reding Quiñones, who plans to use a grand jury in Fort Pierce to investigate a potential conspiracy against Trump.
